To all whoimit may' 'concern Be it knownthat 1, JOHN M. Wirgsoiv, a citizen of the United States, residing at Seneca, in the countyof Thomas and State of rod to prevent lateral strain ebraska, have invented a new7and useful Counterbalancing Attachment forPumps, of

which the followin is a specification.

The invention relates to a device for countor-balancing wind mill operated and other pumps to enable the sameto be operated with a minimum amount of power.

The object of the present invention is to improve the construction of that class of counter-balancing devices having a chain or cable and a counter-balancing.weight, and to rovide means for enabling the chain or cab e to be connected with the pump Without interfering with the operating mechanism of the same. Also the invention has for its object to enable the counter-balancing device to exert a perpendicular ull on the pump and consequent binding and. friction.

. described, illustrated .Vith theseand other objects in view, the

invention consists in the construction and novel combination of parts hereinafter fully in the accompanying drawing, and ointed out in the claims hereto appended; it eing understood that various c anges in the form, proportion, size and minor details of construction, within the 'scope of the claims, may be resorted to with- Specification of Letters Patent. 7 Application filed May 28, 1907.

out departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a side eleva- 5' tion of'a counter-balancing attachment, constructed in accordance with this invention and shown applied to a ump. Fig. 2 is an enlarged detall sectional view, illustrating the manner of connecting the cable with the pump Fi 3 is a detail'perspective view of a bifurcate arm.

nected with the piston of the pump. The pump 2, which maybe of any preferred construction, is provided with an operating handle or lever 3 of the ordinary construction to pum pto be operated by hand when desire he upper end of the shank or rod 1 is coupled. tothe pump rod 4 of a Wind mill; the pump rodfL s provided at its Patented-June 9, 190:3.

will be readily understood. The otherend of the fleiiible connection 8 is provided with a hook 11', which engages an eye or'opening -12 of an arm 13, which is provided with a bifurcated inner portion 14 to straddle the shank or rod 1. The bifurcated portion 14 isprovided with two sides, which are arranged at the side faces of the shank or rod 1, and the arm is secured to the latter by means of a bolt 15, which pierces the-sides of the bifurcated portion of the arm, and which is arranged 1n a notch 16 of the rear edge of the shank or rod 1. The front edge of the shank or rod 1 is provided at a point above the notch 16 with a notch 17 to receive the edge 18 of the arm at the inner end of the bifurcation. The notch 16 has a rounded surface and an upper shoulderto engage the bolt, and the notch 17 is substantially V- shaped to fit the edge 18 of the arm, which extends upwardly .at an inclination. The particular construction forsecuring the arm to the shank or rod 1 ermits the said arm to have 'a limited osci atory movement independent of the shank or rod 1, but the weight niaintains the edge 18 of the bifurcated arm in engagement with the notch 17, and 'thepro ecting portion of the arm holds the inner side of the flexible connection clear r j; ofthe pump rod and the operating mechan Like numerals of reference designate cora responding parts in all the figures of the.v

,i'sm of the pump and prevents the paid flexible comiection from interfering with the operation-bf'the pump. Also the arm enables 'thepountenb ancmg device to exert a direct'upWardmulh on the pump rod, p0 that therewill be no. lateral strain and consequent Thejweight 9 counter-balances the weight of the\pum rod, the piston of the pump and the water 'fted by thepiston, and it will enable the pump to be conveniently operated by hand when desired. Also it will reduce to a minimum the power necessary other suitable support mav'be employed, as

for operatin the pump, and will enable a smaller Win mill to be employed for this pur ose.

Letters Patent, is

min? thus fully described myrinvention, what I 0 mm as new and desire to secure by In a counter-balancing attachment for windmill operated pumps, the combination tion with a rear bearing notch and having an angular notch-located at the front edge of the extended portion a short distance above the bearing notch and forming a stop shoulder, a windmill pump rod connected with and extend ng upward from the said rod, an arm having a bifurcated portion straddling the rod F the pump and engaging the shoulder of the front notchand extending upwardly and outwardly therefrom, a-

fastening device piercing the sides of the 1 bifurcated portion of the arm and arranged i in the said bearing notch and securing the arm to the rod of the pump, a pulley located 2 at one side of the windmill pump rod at a point above the said arm, a flexible connection arranged on the pulley and having inner and outer portions, the inner portion being connected with the said arm and spaced 1 from the said rods and arranged in paralleli ism therewith to exert a vertical pull on the said arm, and a weight connected with the outer portion of the flexible connection.

In testimony, that I claim the foregoing as my own, I have hereto affixed my signature in the presence'of two Witnesses.
